Whoever told you to maintain tire pressure for snow was wrong. You always want to air down for off-road use and even more so in the snow. The challenge with stock tires is that the more you air down, the less ground clearance you have. With an already low ground clearance, you want to keep the vehicle as high as possible while still airing down for better traction.
With my 35" tires on my old Jeep, I would run down into 3-5 pounds for snow sometimes and even went as low as 1.5-2 for deep snow. On my Grand Cherokee with 31" tires, I went down to 12 pounds and was able to get pretty good traction. I do have a CO2 bottle though, so I can air back up easily.
